feat(enters): оприходование товара без поставщика (P1-1)

Domain Enter+EnterLine (мирорит Supply, но без SupplierId и без cost rollup).
EF-конфигурация, миграция Phase6a_Enters (idempotent CREATE TABLE).
Контроллер api/inventory/enters: CRUD + Post/Unpost. Post создаёт
StockMovement тип Enter; Unpost блокируется, если остаток ушёл бы в минус.
Web: /inventory/enters (list + edit), пункт «Оприходования» в сайдбаре
Admin/Storekeeper.

Тесты: 4 интеграционных (post раздаёт stock, unpost откатывает, double
post→409, tenant-изоляция A/B, unpost блокируется при минусе после продажи).
